WINDOW AND SCREEN THEREFOR.

Specification of Letters Patent.

Patented April 14, 1908.

Application filed June 13, 1907. Serial No. 378,694.

To all whom it may concern:

Be it known that I, MATTHrAs A. DIET- RICK, a citizen of the United States, residing at Six Mile Run, county of Bedford, and State of Pennsylvania, have invented a certain new and useful Improvement in Win.- dows and Screens Therefor, of which the following is a specification.

My invention relates to a new and useful improvement in windows and screens therefor, and has for its object to so construct awindow and a screen therefor that the latter maybe secured to the window frame and sash and follow the movements of the sash, the latter being provided with a locking mechanism for holding it against the downward draft of the screen said means also being utilized for locking the window sash when in its closed position.

With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may undcrstand how to make and use the same, I will describe its construction in detail, referring by letter to the accompanying drawing forming a part of this specification, in which Figure l is a front view of a window showing my improvement applied thereto, also showing the screen attached to the bottom of the frame, and to the bottom rail of the lower sash. Fig. 2, an enlarged section at the line X-X of Fig. 1. Fig.3, an enlarged elevation of the lower portion of a window showing the lower sash partly raised, the screen being removed to more clearly illustrate the operation of the locking device. Fig. 4, an enlarged perspective of a portion of one of the shield strips clearly illustrating the manner of forming the hook for retaining the screen rod. Fig. 5, an enlarged end view of the screen roller showing the locking pawl in engagement with the spindle. Fig. 6, an enlarged vertical section of the thumb piece showing the latch in connection therewith.

In carrying out my invention as here embodied, A represents a window casing in which the sash B slides in the usual manner, and to the sides of this casing are secured the shield strips O which are here shown as L-shaped, and each of these strips has a slot D running lengthwise thereof and through which the brackets E pass, said brackets being secured to the bottom rail of the lower sash.

F is a spring roller adapted to be supported by the brackets in the same manner as the ordinary spring shade roller, and upon this roller is secured and wound the flexible screen G having secured to its lower edge the rod H, the ends of which are adapted to engage with the hooks I formed upon or secured to the shield strips, thus holding the lower end of the screen while the raising and lowering of the sash will cause the screen to unwind and wind upon the roller, keeping the window always screened against insects.

The shield strips C by extending a suitable distance beyond the slot D overlap the edges of the screen thus effectually screening the window at the sides while the slots in the shield strips permit the brackets E to travel up and down with the window sash.

In order that the sash may not be drawn downward by the action of the spring roller I provide a spring rod J which is loosely secured to the lower rail of the sash by suitable screws passing through the slots K formed in said rod, and the ends of this spring rod are notched or forked so as to embrace and travel upon the edges of the shield strips as clearly shown in Fig. 3, said shield strips having notches M formed therein into which the ends of the spring rod project when the sash is in its lowered position thus permitting this spring rod to assume a straight position as shown in dotted lines, and in order that the rod may be locked in this position a swinging latch N is pivoted to the sash by a screw which projects through the slot 0 formed in the thumb piece, and when this latch is in a vertical position as shown in dotted lines in Fig. 3 the spring rod will be held in its horizontal position and thus the sash will be locked against being raised, but when the latch is swung sidewise and the thumb piece L drawn upward it will first spring the rod to the shape shown in full lines in Fig. 3 withdrawing its ends from the notches M and permit the raising of the sash, the ends of the rod riding upon the shield strips, and as soon as the thumb piece is released these ends will jam against the shield strips and hold the sash against the downward draft thereof of the spring roller.

Vhen the sash is to be lowered the thumb piece is again drawn upward so as to release the pressure of the ends of the spring rod from against the edges of the shield strips, I to the lower edge of the screen, hooks carried and the sash may then be lowered as will be readily understood.

In order that the proper tension may be given to the spring within the roller F I provide a locking awl P which is pivoted to the end .of the rol er and is adapted to engage with notches formed in the spindle Q as clearly shown in Fig. 5; this arrangement permits the spring to be wound up to the proper tension and when the roller as been placed within the brackets the first movement to unroll the screen will force the locking pawl out of engagement with the notches and suflicient friction is provided between the locking pawl and the end of the roller to prevent the former from again entering into engagement with the notches until forced into this position by hand.

Of course it is to be understood that my improved screen may be applied to the upper sash as well as to the lower sash, and may be used for railway car windows or street car windows, in such cases the roller will be located in the casing beneath the sill and the screen will pass through a suitable slot in the said sill.

Having thus fully described my invention, what I claim as new and useful, is

1. In combination with a Window frame, two shield strips secured to the sides of said frame, said strips having slots lengthwise thereof, two brackets secured to the window sash and projecting through said slots, a spring roller mounted upon said brackets, a flexible screen secured to said roller and adapted to be wound thereon, a rod secured to the lower edge of the screen, and hooks carried by the shield strips with which said rod is adapted to engage, as and for the purpose set forth.

' 2. In combination with a window frame,

two shield strips secured to the sides of said frame, said strips having slots lengthwise thereof, two brackets secured to the window sash and projecting through said slots, a s ring roller mounted upon said brackets, a

eXible screen secured to said roller and adapted to be wound thereon, a rod secured by the shield strips with which said rod is adapted to engage, a spring rod loosely secured to the sash, its ends adapted to travel upon the edges of the shield strips, and means for springing said rod out of a straight line, as and for the purpose set forth 3. In combination with a window frame, two shield strips secured to the sides of said frame, said strips having slots lengthwise thereof, two brackets secured to the window sash and projecting through said slots, a

ppring roller mounted upon said brackets, a eXible screen secured to said roller and adapted to be wound thereon, a rod secured to the lower edge of the screen, hooks carried by the shield strips with which said rod is adapted to engage, a spring rod loosely secured to the sash, its ends adapted to travel upon the edges of the shield strips, and a thumb piece secured to the center of the spring rod for bowing the rod, as and for the purpose set forth,

4. In combination with a window frame, two shield strips secured to the sides of said frame, said strips having slots lengthwise thereof, two brackets secured to the window sash and projecting through said slots, a spring roller mounted upon said brackets, a flexible screen secured to said roller and adapted to be wound thereon, a rod secured to the lower edge of the screen, hooks carried by the shield strips with which said rod is adapted to engage, a spring rod loosely secured to the sash, its ends adapted to travel upon the edges of the shield strips, a thumb piece secured to the center of the springrod for bowing the rod, and a latch pivoted to the sash and adapted to lock the spring rod so as to prevent it from being sprung out of a straight line, as specified.

In testimony whereof, I have hereunto afiiXed my signature in the presence of two subscribing witnesses.
